If spray foam insulation is blocking your house sale, mortgage or remortgage, you're not stuck. We remove the foam to lender standard, provide all the documentation your surveyor and mortgage provider need, and issue a removal certificate backed by a full evidence pack. Same-day reply, written guarantee, no-fix-no-fee.
The problem
Spray foam insulation was sold as an upgrade, but in the roof space it creates exactly the problems mortgage lenders and surveyors watch for.
Sprayed against the underside of the roof, the foam traps moisture against the timbers instead of letting them breathe. Over time that means condensation, damp and, in the worst cases, rotting rafters and battens. Because the foam covers the timbers completely, a surveyor can't inspect the roof structure or spot defects, so they can't sign the property off.
That's why most UK lenders now refuse to lend on foam-affected homes, and why the strictest, including several high-street names, decline them outright. A 2024 BBC investigation found that a quarter of the biggest mortgage lenders, and every equity-release lender surveyed, would not lend on a foam-affected roof (BBC, 2024). Common survey findings are open-cell foam holding damp, closed-cell foam bonded so hard it hides timber condition, and warm-roof spray that blocks ventilation.
The result is predictable: sales collapse, mortgage offers are withdrawn and valuations come back reduced or refused. The fix is professional removal to lender standard, with a certificate.
Selling
Yes, you can sell a house with spray foam insulation, but in almost every case you'll need to remove it first. A cash buyer might proceed as-is, but the moment your buyer needs a mortgage, the lender's valuer will flag the foam and the sale stalls.
Most UK lenders won't lend on a property with spray foam in the roof until it's professionally removed and certified. So while nothing stops you listing the house, the practical route to a completed sale is to deal with the foam before or during the transaction.
Here's what lenders and buyers need: proof the foam has been removed to standard, photographic evidence of the work, and a removal certificate their surveyor will accept. You get the full documented evidence pack lenders and surveyors ask for.
Timeline matters. Your free survey is usually next day, removal is typically 1 to 3 days, and the certificate is issued the same day, so a flagged sale can be back on track within a week.
Mortgages
If your mortgage or remortgage has been refused because of spray foam, you're not stuck, and you're far from alone. It's the single most common reason we're called.
Lenders refuse because the foam hides the roof structure and can trap moisture, so their valuer can't confirm the property is sound security for the loan. What they need to reverse that is straightforward: evidence the foam has been fully removed to lender standard, and a certificate their surveyor accepts.
That's exactly what we provide. We remove the foam, document the work with before-and-after photographs, and issue a removal certificate backed by a full evidence pack. Once your lender has it, the reason they refused is gone. Send your postcode and we'll reply same-day.
Valuation
Spray foam in the roof doesn't just complicate a sale, it can pull your valuation down. When a valuer can't inspect the roof structure and knows most lenders won't touch the property, they down-value it or return the valuation as unsuitable security.
That leaves owners weighing the cost of removal against the cost of doing nothing: a stalled sale, a reduced offer, or a buyer walking away. In almost every case, professional removal costs a fraction of the value knocked off an unresolved property, and it's a one-time fix that puts the home back on the market at its proper price.
Removing the foam and holding a lender-ready certificate turns a property lenders avoid into one they'll happily lend on.
